The rate and magnitude of soil erosion by water is controlled by the following factors: Soil erosion rates are expected to change in response to changes in climate for a variety of reasons. Some of the principal causes of soil erosion include: However, landslides can be classified in a much more detailed way that reflects the mechanisms responsible for the movement and the velocity at which the movement occurs.
This reduction is substantial and long-lasting, and can not be reversed over a lifetime, even with conservation management, low intensity use or high fertility amendments.
Water ways may also be blocked, and it may affect water quality. Loss of fine sand, silt, clay and organic particles from sandy soils serves to lower the moisture-holding capacity of the soil.
Wind-strip cropping is when the strips of crop are place at right angles to the direction of wind. Deforestation, improper farming techniques, intensive agriculture, construction of roads, bridges and dams all lead to soil erosion.
Time for us to conserve soil along with all other forms of life on earth. Some do not function properly because they have no rigid outlet pipe, have an inadequate splash pad or no splash pad at all, or have outlet pipes that have been damaged by erosion, machinery or bank cave-ins.
Reduced organic and fertile matter: Number of Passes Reducing the number of passes of tillage equipment reduces the movement of soil. Things such as earthquakes, floods and even droughts may cause this to happen. Soil Surface Roughness Soil surfaces that are not rough offer little resistance to the wind.
Pesticides and other chemicals can get trapped in soil, polluting streams and rivers as the soil breaks apart. Put simply, it is when topsoil, which is the upper-most layer of the ground, is moved from one spot to another.
As a result, the lack of land cover causes increased rates of soil erosion. Awareness usually occurs only when property is damaged and productive areas of soil are lost. Especially in the developing countries and also in the underdeveloped countries, the farmers themselves are so poor that they cannot afford to implement methods of conservation of the soil.
For example, contour plowing, strip-cropping or terracing may be considered.
Unfortunately, many people are still uneducated about soil erosion, which is leading to the occurrence in greater amounts around the world. Under the right conditions it can cause major losses of soil and property Figure 7.
The erosive force of wind on an open field. Using implements that do not move very much soil will help minimize the effects of tillage erosion. Such a case is evident in North America where dust winds from the Gobi desert have recurrently been a serious problem. Effects of Soil Erosion The consequences of soil erosion are primarily centered on reduced agricultural productivity as well as soil quality.
For instance, clay soils tend to be more resistant to soil erosion compared to sandy or loose silt soils. Many exposed subsurface soils on eroded sites tend to be more erodible than the original soils were because of their poorer structure and lower organic matter.
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species.

Soil erosion is a process that involves the wearing away of the topsoil. The process involves the loosening of the soil particles, blowing or washing away of the soil particles, and either ends up in the valley and faraway lands or washed away to the oceans by rivers and streams.
Soil erosion is a natural process which has. Soil erosion is the weathering away of topsoil caused by water, wind or tillage. Pesticides and other chemicals can get trapped in soil, polluting streams and rivers as the soil breaks apart.
Soil erosion and the effects of soil erosion on crop productivity have become emotional issues and have attracted the attention of agriculturists, environmentalists, and the public in general. Some of the greatest effects of soil erosion include: Loss of topsoil: Obviously, this is the biggest effect of soil erosion.
Because topsoil is so fertile, if it is removed, this can cause serious harm to farmer’s crops or the ability to effectively work their land.Effects of soil erosion
